To all Iwhom it may conce/m.'

Be it known that l, WZYNE L. HArNns,a citizen of the United States, residing atMadelia, in the county of VVatonwan and State of Minnesota, have invented certain new and useful Improvements in Clutches, of which the following is a specification. y

This invention relates to the VAdriving mechanism of motor driven vehicles, fand has for one of its obj ectsto provide` a simply constructed device whereby the drive shaft may be positively and quickly disengaged from the transmission gearing. j

With these and other objeetsfi'n view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention- Figure l is a longitudinal section of a portion of the driving mechanism of a conventional motor driven vehicle including portions of the transmission gearing, the drive shaft, and the universal joint in the drive shaft, with the improvement applied.

Figure 2 is a side elevation of the levers of the transmission gearing with the operating lever of the improved device.

Figure 3 is a side elevation of the main or outer shifting sleeve of the improved device.

Figure 4 is a transverse section on the line 4--4 of Fig. 3loolring in the direction of the arrow.

Figure 5 is a longitudinal sect-ion of the part shown in Fig. 3 without the shipper lever.

Figure 6 is alongitudinal section of the inner coupling sleeve.

Figure 7 is a longitudinal section of the coupling member, detached.

Figure 8 is an end elevation of the mem-v loer shown in Fig. 7.

The improved device may be applied without material structural change to the drive mechanism of motor driven vehicles of various makes, and it is not desired to limit the improved device to any specific construction of motor, but for the purpose of illustration is shown applied to a conventional construction of an apparatus of this class, in which 1() represents a portion of the engine casing, and 11 the transmission gearing including the foot levers 12. In the vided,y one part, indicated atl13, leading from Vthe engine casing and through the transmission gearing, and another part 14 leading to the ldifferential gearing not shown. A universal joint, represented conventionally at 15, is coupled in the shaft section 14, and the part of the latter b'etween the 'coupling l5 and the shaft section 13 is of other `form than round, for instance square as shown'at 17.`

The outer terminal of theshaft sectitm 13 is reduced as at 18,v and bearing vover the re ducedportion 1s a couphi'ig member 19 havlng an attachm'g flange 20 to provide 'mea-ns for connecting the coupling men'herto the` adjacent portion of the icasii'i'g 21 of the transmission gearing 11 as sho-wn at 22.

Slidably disposed over the coupling member 19 is a relatively long sleeve or shell formed of a small portion 23 and a larger` portion 24. The portion 23 is slidable over the coupling member 19, and is provided with a keyvvay 25 in Whicha key or spline 26 in the shipping collar 27 of the transmission gearing engages, so that the sleeve 23-24 will be rotative with the shipper collar and also slidable therethrough. p

The smaller portion 23 of the sleeve is formed with a lieyway 28 in which a key or spline 29 on the coupling member19 enV f and 19.

Formed Within the larger part 24 of the sleeve is a plurality of inwardly directed teeth 30.

Slidably disposed Within the vsmaller portion 23 of the sleeve is a collar 31 having a socket 32 conforming to and adapted to re ceive the irregular terminal 17 of the shaft section 14, so that the shaft section and collar revolve together. The parts 17 and 31 are further connected by a transverse pin 33, to prevent longitudinal displacement. The member 31 is provided with an annular flange 34 having teeth 35 adapted to be engaged by the teeth 30 of the sleeve 23-24, when the sleeve is in one position, and to be disengaged therefrom when the sleeve is in another position.

The portion 24 of the sleeve is formed lwith spaced annular ribs 36 Vto receive the improved.. apparatus the drive shaft is lever41 ,the latterhaving .e holding paw142.

operating over a notched segment 43, attached tothe deck 45 of the vehicle.

By this means, the sleeve 23-24 may be moved longitudinally of the colla-r 31 and the coupling member 19 to disconnect the teeth 30 of the sleeve from the teeth 35 of the collar 31,V to instantly disconnect the shaft section 14 from the shaft section 13. A spring 44 is disposed between the portion` 24 of the sleeve and the adjacentshipper ring' 27 of the transmission gearing, to yieldably retain the sleeve at one end of its movement.

By this simple means the driving lmechanism of the motor can be instantly disconnected from the driving' mechanism of the rear axle, when occasion requires.

The preferred embodiment of the invention is disclosed in the drawings and set l forth in the specification. but it will be understood that modifications Within the scope of the claimed invention` may be made in the construction Without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention. what is claimed as new is In a clutch mechanism, a shell member having internal teeth and a longitudinal internal guideway, an external longitudinal guide channel and an internal longitudinal guide channel, a holding member having a guide rib engaging in the internal guide channel of the shell, a clutch member having a guide portion engaging in the guide- Way of the shell and al plurality of teeth adapted to co-act with the teeth of the shell, a shipper collar slidable on the shell and adapted to actuate transmission mechanism, said collar having a guide rib movably engaging the external guide channel of the shell, means for adjusting the shell longi tudinally Yof the clutch member to couple and uncouple the teeth, and means for independently adjusting the shipper collar longitudinally of the shell.

In testimony whereof, I affix -my signature hereto.
